SHEET-REGISTERING DEVICE.

Specification of Letters Patent. Patented June 13 1922.

Application filed January 20, 1920. Serial No. 352,856.

To all to hom it may concern:

Be it known that I, WALTER E, SMITH, a subject of the King of Great Britaln, residing at Pittsburgh, in the county of Al legheny and State of Pennsylvania, have 1nvented new and useful Improvements 1n Sheet-Registering Devices, of which the following is a specification. My invention relates to sheet registering devices, and especiallypertains to registering devices for use. in connection with platen presses, particularly those of the Gordon t e. v v

1in feeding sheets of paper or the like, especially to platen printing presses, it is usual to provide one or more end abutments and one. or more side abutments on the surface to which the'sheets are to be fed, these abutments being so placed that when a sheet is made to engage with an end and a. side against them it will be in correct printing register with the type in the form. Devlces have been from time to time produced for automatically bringing the sheet, after it has been deposited on the platen or corresponding surface, into engagenemt wlth an end and a side against such abutments. It is the principal object of my invention to improve upon automatic devices of this character and to provide a sheet registermg device which will be of a simple and economical construction, efiicient and accurate in operation, and capable of withstanding heavy and continuous service. Other Ob e'cts will appear from the following specification and annexed claims.

By way of example, I have described one embodiment of my invention in the followinc; specification and shown it in the accompanying drawings, in which:

Fig. 1 is a plan of the platen of a Gordon press, having applied thereto a register device constructed in accordance with my invent-ion, the gripper bar being shown as having rocked so as to lift the gripper from the platen.

Fig. 2 is an enlarged section taken on the line 2 -2 of 1, lookingin the direction of the arrows;

Fig. 3 is asection enlarged further, taken on the line 3-3 of Fig. 1, looking in the direction of the arrows; and

Fig. 4: is an enlarged plan of the register register at 1'5 and 16.

device shownin Fig. 1, in the position which it assumes when the gripper bar is rocked to bring the grippers fiat upon the platen.

The register device is herein described as appliedto the platen of a job press ofthe Gordontype. Such a press includes a platen 10, rockable into and out of printing relation with the type form carrying bed, and having a tympan 11 secured in a place thereon by bails 12. Mounted to rock in bearings car ried by the platen 10, is a gripper bar 13 having adjustably secured thereto grippers 14. When the platen is in and near printing position, the grippers l'pres's downwardly upon the sheet thereon, but when the platen is in position for receiving a. sheet, the grippers 1a, owing to the rocking of the bar 13, areraised from it as shown in Fig. 1. In applying the form ofmy improved device described herein, the gripper bar 13 has portions thereof cut away as A register block 17 is applied to the center of the front of'the platen and comprises a top portion l8 formed with a longitudinal groove 19 having a number of tapped holes 20 therein. Extending down from the top portion 18 is a standard 21, adapted to lie closely againstthe front of the platen, having a flange. 22 extending at right-angles therefrom under theplaten. The flange 22 has'formed' therein a pair of holes 23 which are passed over stems 24, so that the'flange 22 engages from below against collars 25 formed upon the stems 24 and is secured in such engagement by nuts 26, with which the stems are provided. The stems 24 have a threaded connection with the platen and extend therethrough to the top surface. By adjusting the stems in the platen the position of the collars 25 relative to the top suranother of the extending flanges 33 and having a tail piece 3% extending at an angle therefrom and lying upon the upper part of the gripper bar 13 and beneath a bail 25 secured to the rear of the latter.

Pivotally mounted on the base 27 is an arm 36 having its end 37 bent downwardly and then back upon itself at 38, the inner end of the portion 38 being spaced from the portion 37 by posts 39. Vithin the socket thus formed is a plate 40, having its ends upturned to prevent displacement, operated on by a screw ll. In use, the shank of a register finger is inserted in the socket, beneath the plate 4-0, and is clamped in position therein by tightening the screw 41.

To the arm 36 is pivoted, intermediate the end 37 and the pivot about which the arm swings, one end of a link 42, the other end of this link being pivotedto the fiat head Q3 of a pin 44: rockably mounted between the flanges 33 of the short lever 32. The effect of this connection between the arm 36 and the short lever 32 is that as the gripper bar 18 rocks from. the position shown in Fig. 1 to the position shown in Fig. t the link 42 will be pulled to the rear, thus causing the arm to swing .rearwardly about its pivot. y

Secured in the socket at the end of thearm 36 is the shank of a register finger 455 which has at its end a sheet receiving fork 46. A sheet 47 is indicated in full lines in Fig. 1,

engaging in the fork to in an out-of-register position such as it might assume in being fed to the platen. The feeding of the sheets takes place when the register finger and other parts are in the position shown in Fig. 1. After a sheet has been fed, the platen begins to rock toward printing position, and the gripper bar 13 to rock'toward the position shown in Fig. 4. This movement of the gripper bar results in the arm 36 being pulled back by the link 42, whereby the register fork is caused to rock in the are of the circle having the pivot of the arm 36 as its center. In this manner the register fork and sheet 4:? are brought into the position shown in dotted lines in Fig. 1, with one side and an end of the sheet in engagement with the end register abutments and side register abutments, indicated in the drawings as end register pins L8 and a side register pin 49. Perfect register is thus obtained.

The register device described above is of an exceedingly simple construction, and can be produced at a low cost. It consists of a relatively few parts, which latter are of a rugged nature and well able to withstand the hard and continuoususageto which such a device is subjected. The device moreover, canbe depended on. to perform perfectly the function: of] bringing the sheet into correct engagementv with the end. and side register ahutments.
